PURPOSE:To facilitate firing to a solid fuel by providing a U-shaped gas burner at the lower part of a solid fuel accommodating part. CONSTITUTION:When a gas is fed into a gas burner 8 from a gas supplier 16 to ignite the gas burner, a gas combustion flame 17 receives the supply of oxygen from an air intake port 2 and burns to heat and ignite a solid fuel 6 piled up on a grate 9. Since the gas burner 8 is disposed in a U-shape along the longitudinal direction of a main body 1, the combustion flame 17 from the gas burner can heat the solid fuel 6 over a wide range, and hence an effect of propagating the firing in a short period of time can be obtained. |
